1908.0. "De500 100M arp failover" by GIDDAY::SCHWARZ () Sun Mar 02 1997 18:29

    
    
    This is a slimilar problem that has been reported elsewhere without
    resolution.
    
    A customer has a service that has an ip address associated to it ( not
    sure if its a NFS or disk service ). When the service fails over
    DECsafe issues an
    
    ifconfig xx -alias xxxx netmask xxxx and a
    ifconfig xx alias xxxx netmask xxxx
    
    The customer has DE500 network cards and this works fine when the cards
    are set to 10M. Their router does  see a 
    
    src IP=(service IP for www-main) / dest IP=(service IP for www-main)
    
    If they set the cards to 100M this does not occur and they are not
    able to ping the alias address.
    
    They are running v4.0B and Trucluster 1.4
    
    Has anyone seen this before? Any suggestions as to what is going on?
    
    
    Regards
